Pingguo He
Extension Specialist, Fisheries and Research Associate Professor

Pingguo He joined UNH Cooperative Extension and NH Sea Grant in April, 2001. Prior to joining UNH he worked as a senior researcher on fish behavior and fishing gear at the Fisheries and Marine Institute of Memorial University of Newfoundland in Canada. Before that he taught fish behavior and fish gear courses at Ocean University of Qingdao in China. He spent four years at Aberdeen University and Aberdeen Marine Laboratory in Scotland for his PhD on fish behavior in relation to fishing gear. He is a member of Asian Fisheries Society, American Fisheries Society, and Fish Behavior and Fishing Technology Working Group of International Council for the Exploration of the Sea.

• Fish behavior and fish physiology: Fish locomotion; fish muscle physiology, energetics, fish reaction to light, sound, and chemical stimuli; movement of fish in natural environment; effect of environment on fish.

• Fishing gear selectivity and conservation engineering: Design and test of bycatch reduction devices; evaluation and reduction of mortalities of fish encountered with fishing gears but not caught, and mortalities of discards; effect of fishing on the seabed, marine mammals and seabirds; and mitigation measures to reduce these impacts; ghost fishing prevention of lost fishing gears; energy conservation in fishing.

• Fish behavior near fishing gears and in aquaculture cages: Fish reaction to fishing gear components; fish behavior in aquaculture cages, feeding behavior and food utilization; and applications of fish behavior knowledge in conservation-oriented fishing gear designs and fisheries management practices.

• Commercial and survey gear design and test: Design, test, measure and monitor commercial and scientific survey fishing gears; survey methodology, sampling and analysis; flume tank modeling and testing techniques.
